HelloKayBee, When you check the properties of FB452 in General - Part 2, you will find the required length of local data for this block is 380 bytes. When you go in hardware configuration -> CPU properties -> Memory, you will find that the default value for priority class 28 (OB72) is 256 bytes while you require 400 bytes. The 400 bytes comes from the 380 bytes for FB452 and the reserved 20 bytes for OB 72 data. I believe the problem will be solved when you increase the 256 bytes to 400 bytes. Don't forget that you will have to decrease the allocation of local data for some priority classes that you might not use like 4 or 5 (Time delay interrupt OB21 and OB22). Best regards. H-H
